There's also a plug labelled tacho on the loom drawing, I need to ask if this is to connect to a tacho on the bike in which case I don't need to use this plug because I have no tacho, my data logger does all that and has a pickup on the HT lead. My understanding is that the mag pick up is where the efi gets all its timing/rpm info from. The tacho plug has blue & green with white stripe wires just the same as the mag pickup wires.
